To all whom t may concer/it Y Y Be it known that l, DWIGHT '0. lnunnfr'r,

dent of Lima,y in the county of Allen and State ef'Ohio, have invented a neiv and'lfinproved Spray-Nozzle vfor Vertical'Diesel Engines, oi. Which the followingv a full, clear, and exact description. v v l Thisy invention relates to yspiavy nozzles ior the Diesel type of engine and particuk larly to a vertical engine, and has 'for an object to provide an improved construction Y Whereii'i'the oil may he sprayed intoV the en- Y appreciable pressure.

A further object* of the invention is to provide a nozzle for Diesel engines in which means are provided i-or supplying rinea` sured quantity of oil to the engine at interat ya compart of the nozzle is of any desired construcV v"tion, as for instance theorie now in common use, The shell 3 of the nozzle,V may be threaded at the end te fastenV into the cylin der 1, or may he held` against a flange and provided with a gasket'7 or any other means. ln the same manner the core member 5 may he threaded into the shell 3 or clamped in 'position in anyA other suitable manner. 'The` end of the shell 3 is providedVivith'anbore 6 having a threaded section( 7 *for receivingf the spray plug'S Whichmay have one or a number of apertures 9 merging'into Va coni cal shaped cavity 10i? The plug 8 Vmay .be threaded into the shell 3 or heldl by. any

other means in common use. lThe core 2- is` "unioni: Diesen ENGINES.

'Vhat l claim is:

l'. A spray no'lzzle for vertical Diesel engines. comprising a shell formed with a chamber, aspray plug closing one .end 'of said chamber, said plug having` a passageway therethrough, and a central projection extending into the chamber, ancore member having'a central' projection termed with a f bore, said bore providing atrap chamber, the projection on the plug litting into said trap chamber, said core member having also an air passageway leading to the top of said chamber and an oil passageway leading to the topo'r the chamber, an inwardly opening valve for said oil passageway, andan outvwardly opening valve iior the air passageway whereby when air under high pressure is admitted the oil valve will Ye closed and the oil in said chamber will be forced through the` passageway in said plug.

2. A spray nozzle for vertical liesel engines comprising a shell adapted to be vfertically 4 positioned, said shell having a reduced kbore lat the lower end andY a threaded section in said reduced bore, a spray plug :of the shell, said core being provided also with. an oil passageway' leading into the reduced bore olf said shell, and a spring pressed valyeracting in a direction away from said plug Yfor closing said oil passageway, and an air valve positioned to engage the seat in said air passageway wherehy oil inayfl'reely enter the reducedhore of said shell until said valve is unseated whereupon air will pass into said reduced hore and force the oil in the reduced bore through said plug. p

3. spray nozzle Jlor vertical Diesel engines comprising a shell, a plug in the lower end or. the shell Alorined witha reduced top projection, said plug 'liaving one or more passageways extending therethrough andv through the projection, a core fitting into the shell ornied with a hollow projection overlapping the projection on the `plug whereby a trap will be produced, saidY core being provided with a high pressure air passageway merging into theupper part of said trap, and anv oil passageway merging into the upper part oi' said trap, an air valve for controlling the o if air through said air passageway, and a spring pressedvalve acting in a direction away from the plug for closing the oilpassageway.
